Abstract
Methods for improving the mechanical properties of a CDO film are provided. The methods involve, for instance, providing either a dense CDO film or a porous CDO film in which the porogen has been removed followed by curing the CDO film at an elevated temperature using either a UV light treatment, an e-beam treatment, or a plasma treatment such that the curing improves the mechanical toughness of the CDO dielectric film.
